About Tap Water in Dallas, OR

Tap water in Dallas, OR ranks among the best in the state, maintaining a remarkable average water quality score of 88/100 across its 1 ZIP code. Based on recent EPA Safe Drinking Water Act compliance records, water provided by City of Dallas, and other municipal suppliers has consistently met or exceeded federal safety standards. This top-tier "A" grade reflects strong infrastructure, diligent monitoring by Oregon Health Authority, and low contaminant levels.

Over the past 5 years, Dallas has recorded 2 health-based violations. While occasional violations can occur due to seasonal changes or temporary infrastructure issues, City of Dallas, is legally required to resolve these quickly and notify the public via their annual Consumer Confidence Report. The city's water supply, primarily drawn from surface water, is treated to address these specific contaminants.

Fortunately, the modeled risk for widespread lead exposure in Dallas's municipal water is relatively low compared to national averages. However, because lead typically enters drinking water through the corrosion of older, individual home plumbing rather than the main supply lines, residents in homes built before 1986 should still exercise caution by running the tap before use.
